DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a came with connection with a tube stop cock for water supply to the sink and is attached to the wash basin accessory connecting tube with a mixing valve and Haitanku.

[0002]

2. Description of the Related Art In the mixer tap with an accessory connection pipe described above, an accessory water supply connection pipe and an auxiliary hot water supply connection pipe extending below a sink or a wash basin are integrally provided. Connection is easy. The attached water supply connection pipe and the attached hot water supply connection pipe are made of, for example, a relatively soft copper alloy or the like, and are easily bent at the time of construction.

[0003]

However, in winter or the like, there is a problem that the temperature of the supplied hot water drops because the attached hot water supply connection pipe is cooled. In addition, dew condensation may have occurred on the attached water supply connection pipe, causing the floor to corrode. Therefore, a heat insulating material may be wound around the outer circumference of these connection pipes.

[0004] However, in some cases, the heat insulating material absorbs water and corrodes or molds are generated. However, these connecting pipes are arranged in a narrow place such as under a sink or a wash basin, so that cleaning is not easy. There were many things.

[0005] A similar problem also occurs in a straight type water stopcock for supplying water to a high tank.

The present invention has been made in view of such circumstances,
An object of the present invention is to provide a valve with an attached connecting pipe that does not cause a decrease in hot water supply temperature or dew condensation.

An air absorber is provided in the closed space .

[0010]

[0011]

According to the first aspect of the present invention, the closed space formed between the pipe main body of each of the auxiliary water supply connection pipe, the auxiliary hot water supply connection pipe, and the discharge pipe formed in a double pipe structure, and the outer pipe on the outside thereof. Is in a vacuum state, which has a heat insulating effect, can prevent a decrease in hot water temperature, and can prevent the occurrence of dew condensation.

In the second invention, a water supply pipe and a body are provided.
An auxiliary water supply connection pipe connected between the main bodies and a flanged pipe connected between the trunk main body and the high tank are formed in a double pipe structure, and an air absorber is provided in the closed space. by is provided, is a high degree of vacuum maintained, to obtain an excellent heat insulating effect, Ru can prevent the occurrence of dew condensation.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings.

[0014] FIG. 1 is a one-hole mixer tap (with accessory connecting tube mixed
Reference numeral 2 is a trunk body, 3 is a heat-insulating free pipe for discharge, 4 is a heat-insulating cap, 5 is a lever, 6
Is a mounting base plate, 7 is an attached water supply connection pipe, 8 is an attached hot water supply connection pipe, each end 7a and 8a of which has a female inlet 11 and a hot water inlet 12 each having a female screw formed at a lower portion of the body 2 of the body. And are screwed together.

Then, the attached water supply connection pipe 7 and the attached hot water supply connection pipe 8 and the heat insulating flexible pipe 3 (described later) are
Each has a double tube structure made of SUS material. That is, the attached water supply connection pipe 7 will be described.
An outer tube 72 is fitted at an interval to the outside of the container, and a closed space 73 formed therebetween is evacuated .

The double pipe structure of the above-mentioned attached water supply connection pipe 7 is as follows.
It is formed by circumferentially welding both ends of the outer tube 72 attached to the tube body 71 by drawing under vacuum.

The other end of the pipe main body 71 is further extended from the other end of the outer pipe 72 and is integrated with the check valve 10, and the check valve 10 is connected to a water supply pipe or a hot water supply pipe (shown in the drawing). (Omitted). The attached hot water supply connection pipe 8 also has the same double pipe structure.

The one-hole mixer tap 1 constructed as described above is attached to a sink or a sink. for that reason,
Both the attached water supply connection pipe 7 and the attached hot water supply connection pipe 8 are arranged in a narrow and low place. However, since the double pipe structure has a high heat insulating effect, the occurrence of dew condensation is prevented, the trouble of cleaning can be saved, and the temperature of hot water does not decrease.

On the other hand, the heat-insulating free pipe 3 made of the SUS material is also formed in a double pipe structure.

That is, the heat-insulating free pipe 3 is connected to the pipe main body 3a.
The outer tube 3b is fitted on the outside of the tube with a space therebetween, and the closed space 33 formed between the outer tube 3b and the outer tube 3b is in a vacuum state. In addition to preventing excessive temperature rise due to hot water supply, heat conduction from the heat-insulating free pipe 3 to the body 2 can be prevented, and a drop in hot water supply temperature can be prevented more effectively.

FIG. 2 shows a case where the water supply pipe is installed in, for example, a toilet.
Straight type for supplying water to the high tank
In stop cock 51, and supplied with water connecting tube 52 and the flange 60 with the pipe 53 of that obtained by the double-pipe structure, both between the tube body 521 and the outer tube 522, and the tube body 531 and the outer A space between the tube 532 and the tube 532 is defined as a vacuum-like closed space 523 , 533, and an air absorber g is put in the space. 54 is a torso main body, 55 is a valve body, 56 is a handle, 57 is a cap nut, 5
8 is a decorative cover. In this embodiment, the air absorber g, more g, vacuum in the closed space 523, 533 is always maintained, improved heat insulating effect.

[0022]

As described above, according to the first aspect of the present invention, the attached water supply connection pipe and the attached hot water supply connection pipe installed on the sink or sink are each formed in a double pipe structure, and the pipe main body is provided. Since the closed space formed between the outer tube and
An excellent heat insulating effect can be obtained, a decrease in hot water temperature can be prevented, and the occurrence of dew condensation can also be prevented.

Further, the mixing tap with an attached connection pipe is provided with a discharge pipe, and the discharge pipe is also formed in the double pipe structure. In other words, since the discharge pipe is configured as a heat-insulating free pipe, it is possible to prevent excessive temperature rise due to hot water supply of the heat-insulating free pipe itself, and to prevent heat conduction from the heat-insulating free pipe to the body of the body. Can be prevented more effectively.

According to the second invention, water supply to the high tank
The water stopcock with an attached connection pipe for performing the following is equipped with an attached water supply connection pipe and a pipe with a flange, and since each is formed in a double pipe structure, an excellent heat insulating effect can be obtained. , it is possible to prevent the occurrence of condensation.
